A good veggie burger doesn’t have to be boring, and this easy mushroom burger is a prime example. Toss those frozen, packaged veggie patties aside: all you need are portobello mushrooms to make an insanely flavorful vegetarian burger. A simple marinade brings all your favorite burger flavors to our meaty mushroom patty for a taste that doesn’t try to replicate your fave burger, but just might be your new preferred. Bonus: Roasting the portobellos means there’s no smoky grills to deal with for these burgers. It’s a win-win all around. 🙌

Are portobello mushroom burgers vegetarian?
Technically yes, but one ingredient in our recipe isn’t 100% vegetarian: Worcestershire sauce. We love the smoky taste it gives these shrooms, but most contain anchovies, making them not fully vegetarian. If you’re looking to swap it out, look for a Worcestershire that doesn’t use anchovies, or simply swap it out for low-sodium soy sauce.
